Hi group,
I could not find a way to bind a parameter to an incoming value with a
different name. Let's say I have a form which contains an email address
text field with the name "Profile.Email". AFAIK I can't bind it to a
method parameter because of the . in the name. What I'd like to do is
something like this:
public void MyAction([BindTo("Profile.Email")] string email){
// ..
}
Here I define the key of the form value I want SmartDispatcherController
to use when binding the email parameter.
Is this functionality available in monorail yet? I know DataBind of
course, but it binds whole objects, not primitives.
I'm posting this to the dev group because I created a simple solution
for this issue:
[AttributeUsage(AttributeTargets.Parameter, AllowMultiple=false,
Inherited=false)]
public class BindToAttribute : Attribute {
private readonly string parameterName;
public BindToAttribute(string parameterName) {
if(string.IsNullOrEmpty(parameterName)) {
throw new ArgumentException("parameterName must not be null or
empty", "parameterName");
}
this.parameterName = parameterName;
}
public string ParameterName {
get { return parameterName; }
}
}
// overriding SmartDispatcherController.GetRequestParameterName:
// ...
protected override string GetRequestParameterName(ParameterInfo param) {
var args = param.GetCustomAttributes(typeof (BindToAttribute), false);
if (args != null && args.Length > 0) {
var attrib = (BindToAttribute) args[0];
return attrib.ParameterName;
}
return base.GetRequestParameterName(param);
}
It's rather simple but it works for me.
So, my question is: is there already this kind of functionality in
monorail? If so, I'd drop my implementation, otherwise I could polish
the whole thing and provide a patch.
Regards,
Andre
